[TUT] Create your own PPTP VPN using Ubuntu Linux

[chris0147]

Kottonmouth, Could you please help me with my VPN? I'm using Xen CentOS 5.5 64-bit.

I have installed PPTP VPN on my server. When I connect to my server main IP which it is 74.11.33.57. I can connect and get access to the server without no problem, but when I try to connect to another ip which it is 74.11.33.19. I can connect to that IP but the connection is closed after I have connected.

here's the iptables:

Code:

[root@server1 ~]#iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination
SNAT       all  --  172.16.36.0/24       anywhere            to:74.11.44.57
SNAT       all  --  172.16.1.0/24        anywhere            to:74.11.44.19

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
[root@server1 ~]#

Here is the confirguration for /etc/ppp/chap-secrets.

Code:

# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
testvpn         pptpd   mypassword                 172.16.36.0/24
myusername     pptpd   mypassword                 172.16.1.0/24

Do you know what is wrong and do you know how to fix it?
